"This is just a tragedy. It's unbelievable," Garand said as she stood Wednesday near the scene, taping a blue-coloured rose and a small Superman figurine to a makeshift memorial.

"I did that for [Irvine], who I call my Superman," she said.

It was eight years ago that Garand was standing at a bus stop outside city hall, waiting to head to the Transit garage for training.

A man walked past her, grabbed the backpack she had slung over one shoulder, and spun her around. As Garand stood startled, she saw a "blue flash" race past her and return a minute later.

It was Fraser in his Transit uniform.

"I didn't know Irvine at the time, but he went and got the guy and came back and said to me, 'You gotta be more careful,' and kind of gave me tips about Transit and what to expect — heads-up things to a newbie," Garand said.

"I asked him his name and he said 'Superman.' So every time I've seen him, I've always said 'Hi Superman,' because that's who he is to me. He was such a great guy.

"It's just crappy, really crappy. Nobody deserves this."

Garand, who fought back tears as she spoke of Fraser, said she and other coworkers are supporting each other by talking about him.
